Right, OK.
If anyone has one of these Kenwood fridge from Currys
KTLD 60X15
Other colours are (or at least were) available.
and the display on the door does strange things or the buzzer sounds when it shouldn't or the interior light stays off with the door open,
and your purchase date is less than 6 years from when the fault developed (even if it is a repeat fault), then get in touch with Currys and explain the problem.
They may fob you off with "very sorry it's out of warranty". If bought after 1 October 2015, explain that The Consumer Rights Act 2015 applies and quote the following:
The CRA 2015 says that consumers are entitled to a repair or replacement or refund where goods are faulty.
If the fault occurs after six months, the consumer has to prove that the problem was down to a fault or issue at the manufacturer, as opposed to wear and tear or misuse.
The Statutes of Limitations mean that consumers have this right for six years in England (or 5 in Scotland).
In the case of this fridge, it has been established that the breakdown is due to poor design: they are on the third design of wiring loom. So you cannot lose!
